Abstract: The disclosed embodiments relate to the manufacture of a precursor co-precipitate material for a cathode active material composition. During manufacture of the precursor co-precipitate material, an aqueous solution containing at least one of a manganese sulfate and a cobalt sulfate is formed. Next, a NH4OH solution is added to the aqueous solution to form a particulate solution comprising irregular secondary particles of the precursor co-precipitate material. A constant pH in the range of 10-12 is also maintained in the particulate solution by adding a basic solution to the particulate solution.

Abstract: The disclosure is directed to sintered cathode active materials than can be used in lithium-ion batteries. The sintered cathode active materials are prepared by forming a calcinated powder. The calcinated power is combined with inactive components to form a slurry. The slurry is dried and densified to form a green body. The green body is sintered to form the sintered cathode active material. The powder, slurry, green body, and sintered cathode active material have properties that provide improved performance of the cathode active material.
